Many **cloud storage providers** require your full trust that they will not look at your files. The alternatives listed below eliminate the need for trust by implementing secure E2EE.
If these alternatives do not fit your needs, we suggest you look into using encryption software like [Cryptomator](encryption.md#cryptomator-cloud) with another cloud provider. Using Cryptomator in conjunction with **any** cloud provider (including these) may be a good idea to reduce the risk of encryption flaws in a provider's native clients.
Nextcloud is [still a recommended tool](document-collaboration.md#nextcloud) for self-hosting a file management suite, however we do not recommend third-party Nextcloud storage providers at the moment, because we do [not recommend](https://discuss.privacyguides.net/t/dont-recommend-nextcloud-e2ee/10352/29) Nextcloud's built-in E2EE functionality for home users.
**Proton Drive** is an encrypted cloud storage provider from the popular encrypted email provider [Proton Mail](email.md#proton-mail). The initial free storage is limited to 2GB, but with the completion of [certain steps](https://proton.me/support/more-free-storage-existing-users), additional storage can be obtained up to 5GB.
**Tresorit** is a Swiss-Hungarian encrypted cloud storage provider founded in 2011. Tresorit is owned by the Swiss Post, the national postal service of Switzerland.
- This review analyzed the full source code of Tresorit and validated that the implementation matches the concepts described in Tresorit's [white paper](https://prodfrontendcdn.azureedge.net/202208011608/tresorit-encryption-whitepaper.pdf).
- Ernst & Young additionally tested the web, mobile, and desktop clients: "Test results found no deviation from Tresorit’s data confidentiality claims."
They have also received the Digital Trust Label, a certification from the [Swiss Digital Initiative](https://efd.admin.ch/en/swiss-digital-initiative-en) which requires passing [35 criteria](https://swiss-digital-initiative.org/criteria) related to security, privacy, and reliability.
**Peergos** is a decentralized protocol and open-source platform for storage, social media, and applications. It provides a secure and private space where users can store, share, and view their photos, videos, documents, etc. Peergos secures your files with quantum-resistant end-to-end encryption and ensures all data about your files remains private. It is built on top of [IPFS (InterPlanetary File System)](https://ipfs.tech), a peer-to-peer architecture that protects against [:material-close-outline: Censorship](basics/common-threats.md#avoiding-censorship){ .pg-blue-gray }.
Peergos is primarily a web app, but you can self-host the server either as a local cache for your remote Peergos account, or as a standalone storage server which negates the need to register for a remote account and subscription. The Peergos server is a `.jar` file, which means the Java 17+ Runtime Environment ([OpenJDK download](https://azul.com/downloads)) should be installed on your machine to get it working.
Running a local version of Peergos alongside a registered account on their paid, hosted service allows you to access your Peergos storage without any reliance on DNS or TLS certificate authorities, and keep a copy of your data backed up to their cloud. The user experience should be the same whether you run their desktop server or just use their hosted web interface.
Peergos was [audited](https://peergos.org/posts/security-audit-2024) in November 2024 by Radically Open Security and all issues were fixed. They were previously [audited](https://cure53.de/pentest-report_peergos.pdf) by Cure53 in June 2019, and all found issues were subsequently fixed.
An Android app is not available, but it is [in the works](https://discuss.privacyguides.net/t/peergos-private-storage-sharing-social-media-and-application-platform/11825/25). The current workaround is to use the mobile [PWA](https://peergos.net) instead.
**Observera att vi inte är knutna till något av de projekt som vi rekommenderar.** Förutom [våra standardkriterier](about/criteria.md)har vi utvecklat en tydlig uppsättning krav som gör det möjligt för oss att ge objektiva rekommendationer. Vi föreslår att du bekantar dig med den här listan innan du väljer att använda ett projekt, och att du gör din egen forskning för att se till att det är rätt val för dig.
### Minimikrav
- Måste genomdriva end-to-end-kryptering.
- Måste erbjuda en gratis plan eller provperiod för testning.
- Måste erbjuda ett webbgränssnitt som stöder grundläggande filhanteringsfunktioner.
- Måste möjliggöra enkel export av alla filer/dokument.
### Bästa fall
Våra kriterier för bästa fall representerar vad vi skulle vilja se av det perfekta projektet i denna kategori. Våra rekommendationer kanske inte innehåller alla eller några av dessa funktioner, men de som gör det kan vara högre rankade än andra på den här sidan.
- Klienterna bör granskas i sin helhet av en oberoende tredje part.
- De bör erbjuda inhemska klienter för Linux, Android, Windows, macOS och iOS.
- Dessa klienter bör integreras med operativsystemets verktyg för leverantörer av molnlagring, t. ex. integrering av Files-appen i iOS eller DocumentsProvider-funktionen i Android.
- Det bör vara enkelt att dela filer med andra användare.
- Bör erbjuda åtminstone grundläggande funktioner för förhandsgranskning och redigering av filer i webbgränssnittet.
